BEDSTEAD.

To all whom it may concern:

Be it known that I, ALFRED OALvET, a citizen of the French Republic, and resident of Albi, Tarn, France, have invented certain new and useful Improvements in and `Relating to Bedsteads, of which the following is a specification.

The present invention has for its object to facilitate the removal of the mattress from a bed in order to allow of the operation of cleaning being thus easily performed.

In the annexed drawings, given by way of example Figure 1, is a vertical cross section of the invention showing the mattress tilted; Fig. 2, is a detail view; Fig. 3, is a view illustrating an additional detail of the invention; Fig. 4, is a iront elevation of the detail illustrated in Fig. 3.

In the drawings 14 indicates bars secured to the bed and arranged on these bars are stirru s 15y (Figs. 3 and 4) adapted to receive rotata le rollers 16 upon which the mattress 17 is adapted to move by the intermediary of the U shaped irons 18 arranged beneaththe said mattress, the rollers engaging between the two flanges of the said irons.

The length of each of the U shaped irons is equal to the width of the mattress; each iron is composed of two parts connected together in line with each other by means of a hinge 19; one of these members is secured to the mattress on the side where the bed opens; its length is equal to the height between the iioor of the room where the bed stands and the upper side. of the rollers. The other piece or part of each U shaped iron which is connected with the first named part only by means of the hinge, is adapted to move in a horizontal plane above the mattress.

The bed having been opened and the Uv shaped irons being in place upon the rollers, all that is needed for removing the mattress, is to cause the latter` to roll forwards until the moment is reached where the hinges 19 have passed the border ofthe bed; the mattress is then tilted as shown by Fig. 1. As the parts of the U shaped irons which are secured to the mattress have lexactly the necessary length, the mattress will bear upon the floor leaving the bed uncovered as shown by Fig. 1. During this operation, the free 'part of each U shaped iron remains engaged with the upper part of the rollers 16 and in order to secure it in this positionin spite of the rude move ment which might beproduced at the moment where the tilting of the mattress takes place,

each of the U shaped irons 18 is provided at its free end and on each of its flanges with a hook 2O which during the outward motion of the (outward motion) mattress engage stirrups 21 secured to the bars 14. The said hooks equally serve as abutments limiting the motion of the mattress which in this case can only be rolled out on the length necessary for its tilting.

Owing to the above described arrangements, even when the mattress rests on the iioor, it always remains connected with the bed in an unvariable manner and the rolling members remain in contact engagement with each other.

Claims:

1. The combination with a bedstead and a `mattress of a plurality of parallel cross beams secured to the said bedstead, a plurality of stirrups secured to each of the said cross beams, a roller revolubly mounted in each of the said stirrups, a plurality of U shaped guide members parallelly arranged on the underside of the said mattress and each adapted, when the mattress is inposition in the said bedstead, to receive between its iianges and to engage all the rollers of the corresponding cross beam of the bedstead, each of the said guide members being made of two parts one of which is secured to the underside of the mattress, means for allowing of the said mattress to be tilted after having been withdrawn from the bedstead and means to prevent the said guide members to leave th'e said rollers when the said mattress is tilted, substantially as and for the purpose set forth.

2. The combination with a bedstead and a mattress therefor, o'f a plurality 4of cross beams parallelly secured to the said bedn stead, a plurality of stirrups Secured in line to each ofthe said cross beams, a roller revolubly mounted in each of the said stirrups, a plurality of U shaped guide members parallelly arranged on the underside of the said mattress so as to have their flanges turned downwards and to receive between them, when the mattress is in positionin the bedstead, each of the said rollers of the corre-A sponding cross beam of the bedstead, each of the said guide members being made of two parts, a shorter and a longer one, the former of which is hingedly connected to the latter one and is secured to the mattress so as to allow the mattress being tilted after it has been removed sidewise from the bedstead and means for preventing the longer part of the said guide members to leave the said rollers when the mattress is tilted and means for limiting the sideward motion of the said mattress, substantially as and -for the purpose set forth.

3. The combination with a bedstead and a mattress therefor, of a plurality of cross beams parallelly secured to the said bedstead so as to have its upper surface level with the upper edge of the side members of the said bedstead, a plurality of stirrups secured in line to each of the said cross beams, a roller revolubly mounted in each of the said stirrups, a plurality of U shaped guide members parallelly arranged on the underside of the said mattress so as to have their flanges directed downwards and to receive each between the said flanges when the mattress is in position in the bedstead, all the said rollers of the corresponding' cross beam of the bedstead, each of the said guide members being made of two parts, a shorter and a longer one, the shorter one of which is secured to the underside of the mattress and hingedly connected to the longer part so as to allow of the mattress being tilted after having been partly withdrawn sidewise from the bedstead, the length of the said shorter part being such that the mattress after having been tilted is adapted to rest upon the floor while the said longer part remains horizontal, a hook secured to each of the iianges of the said guide members at the free end of the longer part thereof, and stirrups secured to the said cross beams and adapted to be engaged by the said hooks when the mattress is in position to be tilted, substantially as and for the purpose set forth.

lln testimony whereof I have hereunto set my hand in presence of'two witnesses.
